“Self-control is the capacity to alter and regulate predominant response tendencies resulting in the inhibition of undesirable behaviors while promoting desirable ones to support the pursuit of long-term goals.”1 Self-disciplined people are happier. Self-control enables us to manage competing goals. An observational study assessed 414 middle-aged participants on self-control and asked them about their life satisfaction both currently and in the past. The researchers found a strong connection between higher levels of self-control and life satisfaction.2
